We have used the whey powder for several years. It is not whey protein. It is organic and that is good. Whey powder is what is left over of the liquid when making cheese. It has been dried and has much of the nutrients that are in milk. It is used to make whey protein. Now a days there is a lot of talk on whey protein being an excitotoxin. So whey powder is not so refined as whey protein. It is used in many things. We had read that whey powder helps with radioactivity poisoning. It does taste good in smoothies and I use it baking.
